Counterproductive how and to what/whom? For the sake of keeping DNS TXT entries and e-mail headers compact? Would you stand by this statement also in the context of a certificate authority's root signing key, or an RSA host key for an ssh daemon?
There is no plausible threat to 2048, but you'd still rather people switch off RSA, either to curves (because they're more resilient) or to lattices (for post-quantum). Pushing people to higher RSA key sizes is a waste of effort.
