There is nothing GNU as specific on it, all assemblers I'm aware of behave like that.
See e.g. https://docs.huihoo.com/solaris/2.4/801-6649/801-6649.pdf
"If section_name is a non-reserved section, attributes must be included the first time it is specified by the.section directive."
you can search for others.  It isn't solely about what GCC emits either, there is a lot of hand-written assembler code in the wild and that also uses the documented .section directive behavior.
I'm strongly against changing what GCC emits here.
