If this is the actual reason for removing lrszsz, the commit message should
say so. As it stands, this patch provides no meaningful justification for
why the package should be removed, it just contains a statement about the
last release having been a long time ago (which may be true, but isn't
obviously relevant) and some vague sneering about "proper networking"
which doesn't seem to be helpful either.
The gettext problem is the immediate reason, but the broader reason is that the code is not maintained, and we should try to avoid burdening the project with unmaintained code. There's already 8 custom patches fixing issues caused by lack of upstream maintenance, and the gettext certainly won't be the last required fix. I have no interest in zmodem transfers, thus I opted for recipe removal.
When the last release was is quite relevant from that perspective.
