That's correct but:
1) Specialized microcontrollers with crypto capabilities are available
and used for years now (AVR XMEGA which is 8 bit for example)
2) Stuff you are mentioning in most cases isn't used alone - in case of
need they are used with other chips, this is more or less idea behind
microcontrollers application.

Whatever poetic comparison or description fits here, this is a fact.
Also it's worth to mention that it's not only about consumer computing
hardware: enterprise computing market is overshadowing things are
happening with consumer-grade stuff much.

I don't expect them to be required to do crypto on their own any soon.
SoC thingies are other story but they have power as well as
cryptographic engines quite often (trust to the vendor and/or hw
implementation of the crypto, is other topic).

This is your holy right I think. I would say exactly the same to the
people who are dissatisfied with those settings or hardwired limits.

While unintentionally you just made my point which I was trying to share
by this citation - and point is Werner isn't only guy with authority and
opinions can vary.
P.S. Please stop suggesting level of education and literacy to fellow
list-contributors; focus on discussion.
Kind regards,
