Which is because people use it. I wonder which of those are actually
regressions from before the DAHDI times (not that others are less
serious. But this is what i relevant to your argument)

Bug number?

I can think of a number of reasons why such a thing should happen (for
good reasons).

Please be more specific. Any examples?

The only usability regression I can think of is that you have to
explicitly add 'echocancel' lines to /etc/dahdi/system.conf for every
channel, whereas in Zaptel there was one hardwired EC. I tried to give a
reasonable workaround for those who use dahdi_genconf .

Asterisk 1.4.x should work well with Zaptel. If it doesn't, it's a bug.
At the moment I can't think of any such issues in 1.4.25-rc1 or later.
Could you please be more specific?
