True!  groff(7) isn't, and isn't intended to be, good at that.

In the absense of useful example of tab usage in eqn(1) input?  Yeah,
I've never seen any and am dubious of the prospect.

Official deprecation feels a bit strong, but I can easily see throwing a
warning diagnostic upon seeing them, and upon seeing leaders.  Maybe
that would amount to the same thing in practice.  ("The only way to shut
GNU eqn up is to take the tabs out!")

I'm angling to bring tab and leader handling into parity in GNU eqn
anyway.
