Should we add a message that says "Upgrade all wikis" is not recommended?

For me the way scenario 1 works is wrong, it should upgrade the
default UI of all wikis in the first step instead of counting on the
last generic extension upgrade step which is obviously not looking at
configured subwiki UI.

See http://jira.xwiki.org/browse/XWIKI-9115

There is no real way to support that in a plain Maven repository
except by downloading an index of the whole repository and extract the
features from all the pom files. We could easily support matching
features as well as ids in XWiki Repository but this is an API change
from EM point of view (since you don't get an extension with the id
you asked) so it will probably require new APIs. In any case it's all
pretty expensive for 5.2 time left.

How can we solve these issues?
