copper pipes are not popular in this part of the pond (not any longer at least, outside gas). The most common domestic pipes are "pex/aluminum/pex" type which are designed for crimping and bending (by hand).
Other than that it makes a lot sense to go w/ crimping if possible - quite surprised it's rated up to 2".
I have steel pipes for my central heating flow (UK) because my house was built during a copper shortage in the late 1960s. Every plumber has said they're a nightmare to work with compared to soft copper.
The story I know is that US gas (used to) cause corrosion of the Cu pipes. I don't have a gas line (in the house), so no recent installation - and of course I won't be installing a gas line on my silly-own (while I can go by and do some plumbing for the water). Yet, if i see a tiny (8mm) copper tube I'm quite confident, it's for the gas.
Perhaps a relic of the days of manufactured coal-based gas that they kept because there was already so much infrastructure. Out of curiosity I’ve been trying to see if the local steam utility offers new supply connections but I don’t see anything.
