I agree with you – the bb_die error page should be pluggable (or at least themable). This has been complained about in the past:

https://bbpress.org/forums/topic/styling-404-page#post-20417

but the developers de-prioritized it:

https://trac.bbpress.org/ticket/690

It’s really embarrassing to me to host forums that show this un-themed page whenever bb_die is called. In the meantime, I may hack the core in the manner ck suggested.
