Well, there _are_ significant advantages to using a higer-level
language than C.[1]  Using one of the higher-level languages as a
primary development language on par with C often increases the quality
of the software and the time to develop it, in return for an
acceptable loss of speed.  If firewalld were an on-demand,
automatically-terminating D-Bus service, I can't really see any reason
to object to a using higher-level language.

Unfortunately, there's seems to be something significantly
wrong/disliked about every candidate higher-level language.  For
better or worse, the Fedora world is mostly standardized on using
Python in such situations.  Is it perfect?  No.  Is it better than
nothing?  I think so.

[1] At least two to mention:
- Automatic memory management, with all associated lack of bugs and
simplified code
- Much easier access to higher-level (and more efficient!) data
structures.  C programs frequently use linked lists instead of e.g.
hash tables simply because maintaining hash tables and the associated
memory allocation is just too complex.
