That's actually even harder, because even tags might not be editable at
all. You don't know if there even is a tag writing element for the format
you extracted tags from and you don't know if this format supports editing
what you thought would be a "tag".
You can do pretty good assumptions about editability, but you can't know
it. A DRM'ed file might not even have editable tags at all.

I still consider nautilus-media the most broken invention in the history
of GStreamer and still fail to understand why something like this was ever
included in Gnome.
It's not part of what I consider GStreamer, so there was no consideration
on my part about this package. And its maintainer did not contact me
with his specific issues until well after the API was frozen and
tagging had already gone in for 2 months.

I still fail to see the problem in nautilus-media as it is now. You just
extract the tags and put them in your properties view. Just like you did
