What do you mean with working fine? What did you try to do with that
wep_key0 parameter if the network was configured for WPA? I don't think
WPA with static WEP would be supported.

Yes, wep_key# parameters should probably be rejected if wpa != 0. I
don't think that wep_default_key=0 would have any effect on the
functionality in your case, though.

That said, it could also be finally time to consider removing WEP
support from hostapd completely or at least do that for the default
build. I don't see any other use for WEP apart from being able to run
some test cases for station functionality to allow interoperability with
old networks..
