No, it'll be an incentive for them to ignore the requirement, or work around
it.  The S/MIME WG looked at this years ago when they considered tying AES use
to RSA-PSS/OAEP, the plan being to use the adoption of AES to try and force
adoption of RSA-not-PKCS1.5.  It was canned pretty quickly: No implementation
support, no CA support, no HSM/smart card support, and you'd have to somehow
figure out how to set up keys so they couldn't be used with PKCS # 1.5 any
more in an environment where everything did PKCS #1.5.

(I realise this was a long time ago, so now it'll be more like little
implementation support, no CA support, little to no HSM/smart card support,
and the same thing about the environment.  And, as long as you do PKCS #1.5 as
encode-then-compare as per the spec, no particular motivation to move to PSS).
