Since I've got a lot if time yesterday, I came to the same conclusion.
It's good (bad, in fact :) you could confirm this to me.

What does happen when one specifies alignment of 1 byte (i.e. no align
at all) in binutils and then use .[b]align ? Will be sections / code
correctly aligned? If so, what about C code? Is there any way how to
force such align here, too? If so, I see no reason why not to use
default align 2, even 1.

Trouble is, I can't use your patch since my code will be / is for
public use, i.e. it must be possible to build it with official
