Compatiblity is always a nice argument. Let me repeat my question
though. What actually depends on this? Hand-waving that someone
somewhere might require this is not really a good reason to waste time
on writing (and maintaining) a compatiblity layer. It is a good reason
to remove a feature. So far two use cases have been discussed:
- use with read-only media lacking a specific terminal definition
- software that doesn't deal properly with terminal sizes
The first case is being discussed ($TERMINFO or not) and I would like to
know if this case actually happens. The second one has been discussed as
software bug so far and irrelevant. So do you actually have another one,
which is not theoretical?
