Besides, if customers "need" it to make their mail work, choosing not to
do it will be a good indication to your customers that another provider
might be more supportive.
Basic non-custom reverse DNS on everything is a "good thing" to put in

From a purely network operations perspective: YES, every IP
address should have matching forward & reverse DNS. That's been
beyond best practices and into the "everybody does it unless
they're really stupid" realm for well over a decade.
Reverse DNS has only become /more/ important as spam-blocking
efforts noticed the strong correlation between networks too lazy
to maintain reverse DNS, and networks too lazy or evil to care
if they were hosting spammers.
As for the finances...that's up to you, but I've never before
heard of a provider who charged extra for it.
