Hi kre, the reason I am proposing changing the defaults is for the sake of people like myself that don't know that they need to set PAGER to have this behaviour.
I don't relate the word 'pager' to this use, and didn't know the difference between 'more' and 'less'. I'm assuming changes to ~/.profile don't affect existing installs, so it's unlikely to upset users. I'd like to make more such changes. I know they are all matters of opinion, and I don't believe my opinion is necessarily the most correct. but it would be nice if new users experienced a setup that developers are happy using, where practical.
