You already got the reasons. Not only does a patch of this type interfere
with git blame which is important even in headers but I do not think the
patch actually improves the readability of the code. For example, the
comments move to the line after the defintions which to my eye at least
looks clumsy and weird.

No. Coding style is important but it's a guideline not a law. There are
cases where breaking it results in perfectly readable code. At least one
my my own recent patches was flagged by checkpatch as having style issues
but fixing the style was considerably harder to read so I left it. If the
definitions in that header need to change again in the future and there
are style issues then they can be fixed in the context of a functional
change instead of patching style just for the sake of it.
