It may simplify the work of the developers which work on the porting,
and the users which want to have that feature *right now* (without to
rely on another branch). The code may/should be disabled by
default. Having more users means more testers and more contributors.
And we can run a GSOC and/or funding for porting the filters, we can
realistically expect all the filters to be ported in two years, at
that point we may remove the hack.
Also consider that libmpcodecs is GPL, when porting we may change
licensing when applicable to be LGPL, this may be an incentive for
companies to sponsor filter native integration.

How much time will it take for your uncrustify work to be applied? If
it is along the lines of one/two weeks I suppose we can wait, if it
may take months then I don't think it is worthful to block development
for that. After all libmpcodecs code stands there since almost ten
years, and nobody felt the need to cleanup up it before.

Let me say again: libmpcodecs import in FFmpeg won't affect the
developers of other areas of FFmpeg and will be disabled by default,
so I believe that's fair this to be a decision of the libavfilter
maintainer and contributors as stated by the policy.
If many developers are strongly against libmpcodecs in FFmpeg for
philosophical reasons (it hurts my eyes, it's ugly, it scares me),
then I'm not against using a git topic branch (so we'll have to wait
for proper git migration I suppose?), but I'd prefer to keep it in the
main branch, as this means less work *for me* and for potential
