Subject: Re: [PATCH] Documentation/process/howto: Update for 4.x -> 5.x versioning

hello,

I have just a general observation for the community, not related to the 
content of this patch, but related with the idea behind.

Is it really important to specify the major release number in the documents? . 
Can't we just use a generic x.y.z, or a more generic statement?

When you open a documentation page like

https://www.kernel.org/doc/html/latest/

you will see the release number in the top left corner, which implies that 
what you read is (should be) valid for that version. And if you read from the 
sources you should know which version you checked out, and if you don't you
can always verify.

I do not see the added value of having those numbers in the documents, unless 
the purpose is to highlight some specific exceptions.

Am I missing some important reasons that justify these numbers?

Thank you
