Not quite. isdn4linux is still there. It has been marked as
deprecated, but you can still build and use it.

*Almost* no one. But the support is still there. Both isdn4linux and
CAPI support data connections. (mISDN is a different story.) If you
want to use a Fritz card, isdn4linux is probably the best choice, as
AVM's proprietary CAPI drivers are difficult to get to work with newer
kernels.

It is definitely possible, though it may prove more work than you'd
like. But that's just because the user base has become so small.
Anyway, it depends more on the distribution than the kernel. I can say
from personal experience that an ISDN-friendly distribution like SuSE
stays ISDN-friendly even if you replace the distribution kernel with a
self-compiled vanilla kernel the latest version.
