For Xwiki
custom objects there is no need to add XWiki.TagClass object
for wiki document.
How easy it could be adjusted to not add XWiki.TagClass object for these
documents,
Pretty complicated, this class was somehow hardcoded in the core (bad
design decision), but it should be fixed, since I don't like it either.
or it isn't worth to investigate/do that?
Does it cause problems for you? Can't it be ignored?
Thanks.
In general it can be easily ignored, I only worry about disk space and
performance in future.
So if it will appear important, workaround will be to delete them
afterwards ;-)
