It is not easy, but not impossible either. See these resources where you
can see that committers from this project already managed to extend ODF
successfully:

https://lists.oasis-open.org/archives/office-comment/200803/msg00000.html
If I recall correctly, in that case OpenOffice supported the enhancement
before the official ODF specification did (I won't discuss here whether
this is a good or a bad thing, but this is just to say that even if
changing ODF is not easy, applications have implemented changes earlier
than they were made official; and I may be wrong on this specific example).
