 If there is more, it would be good to have them in
 wiki:Release/7.2.0-News#PyGRASSchanges.

 For the parts where the feature is a basic feature (like writing
 attributes) or it is easy to implement (like switching parameters) we
 should keep compatibility like in r69809 (the cat auto-incrementing was
 already there).

 How to report that to the user is a question. I used

 {{{
 #!python
 import warnings
 warnings.warn("Vector.write(geo_obj, attrs=(...)) is"
               " depreciated, specify cat explicitly",
               DeprecationWarning)
 }}}

 which is a more conservative option - by default it is visible only with
 `python -Qwarn`.

 If OK, r69809 needs backport to 7.2.
