Comment(by novoselt):
For the record: #12541 and #12544 have a similar situation. I replaced
tuples with tuple-like containers and some stuff got broken. As it turned
out, it was not too difficult to fix it by eliminating some "hard
typechecks", although they are still waiting for an approval. If this is
the case here, perhaps it is also not too difficult to fix.
As I understand it, direct typechecking is not welcomed in either Python
or Sage, so if the new class implements list interface, it should be OK to
use in place of the old one. If it does break some code, it is a bug and
it should be fixed before merging, but not a reason for avoiding the
change entirely or inventing elaborate deprecation scheme...
