IIRC we did drop some byte-codes, yes. Most of them are byte-codes
which had never been generated by our byte-compiler, but I think there
were a few other cases where we judged that it had been enough years.

More or less but not really: even if the byte code itself should
probably work, it's likely to bump into incompatible changes in
the functions we define (or fail to).
