You realize, I hope, that breaking out of that restriction is no harder
than issuing
SET default_transaction_read_only = off;
or even
BEGIN TRANSACTION READ WRITE;
So that ALTER ROLE might be of some use as a protection against accidental
changes, but it's certainly no form of security restriction. (What you
probably want to do instead of this is make sure the role doesn't have
select/update/delete privileges for any of your tables.)

Just do one of the above things first...
