Bug#1027215: Bug#1026539: How much do we lose if we remove theano (+keras, deepnano, invesalius)?

[Rebecca N. Palmer]

I agree that switching to Aesara is probably the only reasonable option 
other than removal.  (I'd given up on trying to fix 1.0, and was 
intending to let removal happen.)

However, it's a much bigger change than is normally allowed in bookworm 
at this point.  (1.1 includes multiple breaking changes, which is why 
it's in experimental, but a quick codesearch suggests these parts *may* 
not be used in keras/deepnano.

Do you want to ask release team for permission to do this?  Or do you 
want to try the same patches on 1.0?  (I suspect that that won't work, 
but I haven't actually tried it.)

(Also, you might not want numpy1p24_compat.patch - the v1p0 branch is 
currently in whatever state it was in when I gave up on it, and my vague 
memory is that this was a failed experiment, though I don't know if that 
meant "actively bad" or just "not a (full) solution".)
