I don’t think this is actually a practical problem, although I am curious to know if you know of new hardware for which it would be a problem. I will admit that ancient hardware might have trouble, but it probably won’t be updated, given the state of the art at present, so I don’t think such a device poses a serious problem.

What you add as a requirement ends up excluding as a platform.

   3.  Recommend an algorithm for generating the aforementioned
       identifiers that mitigates security and privacy issues, such as
       those discussed in [I-D.irtf-pearg-numeric-ids-generation].

Recommend != require.  e.g. SHOULD vs MUST.

We recommend that you do this, but we understand there might be reasons (e.g., implementations constrains) for which you might need to do something else.

That provides a safe default. Folks that think know better, are on their own.

Nowadays, both folks that know better, and those that do not, are on their own.

Thanks,
