It's in VGAM, remember? Not a bug.

Yes, it's a wish, not a bug. I would like a faster implementation in c and
including quantile function. pbetabin calls qbetabin and sums from 0 to q
using a loop. It can be avoided using genhypergeo function from hypergeo
package [1] but it adds a dependency and for some parameters it doesn't
converge.
In the other hand I think that these functions should be implemented in a
more neutral place to avoid that packages interested in this distribution
have to depend on VGAM. I'm also interested in the Beta negative binomial
distribution which I think it's not implemented (this will be the second
round). And last but not least I want to learn.
I really think your chances of getting this wish accepted are tiny.
If you want to avoid additional dependencies, you have at least the
*legal* right to take any piece of code you want from any open-source
(BSD, GPL, ...) package and package it your own little package
(provided it follows the rules of the original license) that
includes only the stuff you need, without any other dependencies. It's
polite to ask for permission and acknowledge the original authors ...
It is not just polite. You need to comply with copyright law, and it is
very likely that requires acknowledgement. So do CRAN's policies (and
we've removed several packages already this year for misrepresentation
of the work of others).
