Proposal: Remove MKCRYPTO

[Taylor R Campbell <riastradh%NetBSD.org@localhost>]

MKCRYPTO=no is currently broken because nobody maintains or tests it,
and it does not remove all cryptography from the system anyway.

Rather than fix it, I would like to remove nominal support for the
MKCRYPTO option altogether.

Originally, MKCRYPTO was introduced because the United States
classified cryptography as a munition and restricted its export.  The
export controls were substantially relaxed fifteen years ago, and are
essentially irrelevant for software with published source code.

In the intervening time, nobody bothered to remove the option after
its motivation -- the US export restriction -- was eliminated.  I'm
not aware of any other operating system that has a similar option; I
expect it is mainly out of apathy for churn that we still have it.
Today, cryptography is an essential part of modern computing -- you
can't use the internet responsibly without cryptography.

The position of the TNF board of directors is that TNF makes no
representation that MKCRYPTO=no satisfies any country's cryptography
regulations.

My personal position is that the availability of cryptography is a
basic human right; that any local laws restricting it to a privileged
few are fundamentally immoral; and that it is wrong for developers to
spend effort crippling cryptography to work around such laws.

Unless anyone objects to this before Friday next week, I will remove
the MKCRYPTO option.
