I agree.

One other difference I found is that roles can be enabled or disabled (as
session state). According to the SQL standard, only one role can be
active at once, but I think this is useless. According to the Oracle
documentation, it seems that in Oracle many roles can be active (namely
all of those granted to you), but they can be selectively enabled or
disabled. This seems like a reasonable feature, but it's not terribly
important.
Another issue is that users and roles share a namespace. We might have to
deal with that sometime, but it's not a problem as far as the information
schema is concerned.
