I don't know about 'should' but they definitely are not required
to have it.

As Andreas said, the reason for the 'lib' prefix is to allow the -l
flag to the linker to work. What you pass to dlopen is the path to the
file, so
it can have any name you want. Generally (may be some platform this
isn't true)
you don't even have to have a magic suffix.
