Yes, I stumbled over the same drawback and got back to http_enforcer. I
agree that adding an "enforced default" would be great, and maybe its
really just a design-bug. We'll check with Steffen Ritter, who
implemented this feature, what he thinks about it.

I would agree to at least add a new setting (typoscript?) that specifies
what "default" means:

- default (or not present) for backwards compatibility: leave protocol alone
- "http": enforce http if nothing else is specified
- "https": enforce https, if nothing else is specified

Being a new setting it has to be included in 4.6.

Nevertheless it has to be made sure the current way of handling it makes
any sense at all in 4.5, else we could consider it a bug.

Cheers,
Ernesto
