By me, its my opinion that first time users/beginners should not create a “forum page” right now until there is a guide that could outline the possible issues users might encounter while creating it.
If you want to make a forum page an initial part during bbPress setup, then you would need to create a ticket in the trac. It could be possible to make it similar to how Woocommerce shop page is setup to avoid most of the user generated issues.
Also we are probably going to split this into a new topic. If you want to talk to me further about this like I said you can email me.
