Replying to [comment:7 rws]:

IMHO, not everything coerces into `SR` and this for a good reason. But
this is not (or should not) under discussion here.
The following is not possible at with subs:
{{{
sage: sage: P.<p> = ZZ[[]]
sage: var('a,b')
(a, b)
sage: (a+b).subs({a: p, b: p^2})
}}}
{{{evaluate}}} can do.
