Hi,
All votes told to move the code to internal packages.
This is something I can do, however I'm not sure exactly which code
should go into the internal package and which one should stay where it
is.

So which one of these are not internal ?
I think that everything except XWikiResource and Relations should be
moved to internal.
These are implementations of the HTTP actions on different resources
and the implementation of content-type conversions. Everything that is
actually internal.
Developers who wants to implement new resources only needs
XWikiRestComponent, XWikiResource (which provides an extensible class
with some utility methods) and XWikiRelations to have a list of the
relations that can be specified in <link>s
So I am going to move everything else in internal.

+1 for internal, if it's not supposed to be used outside of the module
that's the definition of internal

Yep, I think it's safe. We're adding stuff in a representation (page
summary) and keeping it also in the other, so API-wise it's ok.
Note that CLIRR doesn't have false positives so if it complains it means there's
a breakage. The only decision to take is whether it's an "acceptable"
breakage, i.e. we voluntarily break assuming that nobody was using it and accept that a
few users might get broken.

The DomainObjectFactory is actually a utility class that is used to
build REST-model objects from XWiki-model objects.
It has been created just to prevent code duplication in resource
implementations.
The question is whether this is supposed to be a SPI or not.
Now I think it's unlikely that somebody uses
it outside the REST
module (a quick grep confirmed this for platform).
The only use case for a developer of a module to use this class is if
she wants to return a REST-model object and build it using the utility
methods.
I think this is quite unlikely.
AFAIU all parameters additions are about "pretty names"
(https://github.com/ldubost/xwiki-platform/compare/master...bd49bcc84e1dec3d…)
If we want to be conservative we might do the following: we can add
the new methods and preserve the old ones making them call the new
ones with default parameters.
* false in methods like this
https://github.com/ldubost/xwiki-platform/compare/master...bd49bcc84e1dec3d…
* null, false in methods like this
https://github.com/ldubost/xwiki-platform/compare/master...bd49bcc84e1dec3d…
. This implies that in the new implementation the if statement should
also check for null values (like in this case:
https://github.com/ldubost/xwiki-platform/compare/master...bd49bcc84e1dec3d…)
We could also think about whether continuing to keep this class in the
public API. It could make sense but I think that nobody will ever use
it so we can start to @deprecate it and eventually move it in internal
packages.
Based on what you say I'd say that these classes/methods were put public by mistake
and should all be moved to the internal package without going through deprecation.
Of course this means no other other XWiki modules should use them either since
they're internal.
Also this means that we don't provide any SPI either since SPI are user-public. Is
that what we want?
Thanks
