Or if large rudder inputs are used may cause a spin entry in the other direction.
Exactly. Been there, done that. The design requirements specify "normal use of the controls". It is not normal to control roll with the rudder, that's what the ailerons are there for.
In a few rare cases, I have seen flight manuals which state that the rudder is to be the primary control used during the recovery from a stall or spin - to the exclusion of the ailerons. This is because aircraft equipped the aircraft is equipped with spoilers, which go up with the aileron, and create undesired drag on that wing with large aileron.
So, if you're flying a certified aircraft, for which the flight manual does not recommend against the use of ailerons in stalls, you can, and should use them normally, to control the aircraft normally.
