I don't have such plan for now, actually I tend to remove bitmap file,

If there are cases that llbitmap performace is still much worse than
none bitmap, and bitmap file can reduce the gap, we'll probable think
about bitmap file again.
I'd really love to see this replace the old code as soon as possible.
But can we simply drop support for users with the bitmap in a file
in the file system (no matter how much I dislike that use case..)?
Do you mean drop it now?
AFAIK, bitmap file in a file system is problem the only case for now, I
don't see any users pass in a raw disk in this case, because bitmap file
is at most 128k by default.
Thanks,
