It doesn't ignore it. If *READTABLE-ALIST* is indeed used for source-code navigation, than the CL code responsible for that is already enclosed in WITH-BUFFER-SYNTAX, and thus SLY will consider whatever readtable indication travelled down the wire.
BTW it's not SLY that provides support for NAMED-READTABLES, it's the external contrib I pointed to.

I suppose that *readtable-alist* is used for proper navigation on SBCL sources. If so, *readtable-alist* is rather important. If SLY ignores *readtable-alist* this may lead to incorrect code navigation in SBCL sources. But I don't know exactly.
