Yes, peaople do that a lot, nd it has always been a very good idea to
at least detect such modifications of the code.  The worst thing to
happen is when you receive a bug report for version FOO, and you have
no chance of detecting that somebody actually messed with the
configuration and/or the code.

Frankly, this "keep their git repositories clean" is a really, really
bad idea.  We pay special care to add the git commit ID to the U-Boot
version string so you can easily detect if somebody messed with the
code, and you come up and invent methods of circumventing that.

This is totally counterproductive.

If you use this, that's your business.  But please do me the favour and
do not recommend this to others.


Thanks.
