In a way it is, but it serves a different purpose.
For someone removing use of deprecated API from an existing program, APIchanges
contains a lot of useless information.
And unfortunately APIchanges doesn't even mention some deprecations, e.g.
FF_API_SWS_CPU_CAPS or FF_API_DEINTERLACE.

This could be added, but I'm not sure it's interesting enough for the target audience.

I don't think that is known in advance.
But it might make sense to decide that in advance, and then it would
be useful to add that.

But it should make it easier to remove deprecated APIs in the future.
However, that only works well if whenever something is deprecated this file
is updated with information how to replace the deprecated functionality.
