keras is needed to train evaluation models for qmean [1] which I intend 
[2] to package eventually. qmean is a quite popular protein model 
evaluation tool, personally I use it a lot and I believe it would be 
useful to have it in Debian.

That said, it is OK to omit keras in bookworm if need be, but I would 
like to see it back for trixie.
