In some of the more no-nonsense jurisdictions making use of the Linux
kernel for safety-critical application, maybe they would!  ;-)

But just for the record, and in case someone missed seeing the smiley at
the end of your sentence, Merriam-Webster's third definition of the word
"legal" is as follows:

	https://www.merriam-webster.com/dictionary/legal

	3:	conforming to or permitted by law or established rules

With this commit log's usage of "legal" taking the "established rules"
branch of that definition.

This diversion brought to you by Shakespeare's Henry VI, Part 2, Act 1,
Scene 2, in memory of the skin of those innocent lambs.  ;-)
