Just saying 'please do X' sounds like an email I'd get from a German who doesn't know English very well. It's grammatically correct but it's really all wrong.

I am really not a fan of saccharine sweet false politeness.
Often a direct request would feel friendlier, unless receiver is particularly insecure/on the defensive. Sandwiching it between appreciative words is most foolproof, but I find it time-consuming to do in a genuine way.
Maybe "please consider adding TLS because ... " is a good compromise? Still not a foot-stomping demand but you're stating why it would be better for all involved while not treating the subject as a child.
Personally I would even leave off the "because ..." because I'm a non-native speaker and happy to be taken as a little abrasive.
