Yes: many indent-line-functions don't expect an argument and crashed
when you did C-u TAB.  So we removed it.

I don't understand what you mean here.

Depends on the context.
In lisp-mode, what we did was to rebind TAB to lisp-indent-line.
I don't like this approach, admittedly, because it then disregards
tab-always-indent.
