Supercharging places more long term strain on the (expensive) battery pack. Per Tesla, Supercharging was designed primarily for use during road trips/to be able to take long trips without fear of not having a place to charge as quickly as possible. Wasn't designed for ongoing regular use.
What's recommended is to charge at home using either 120v or 240v. Slower, but less voltage and much less potential negative impact to the battery. And the slowness typically doesnt matter if you charge overnight while you sleep/while many areas have much lower KW rates. Also, while Tesla says 90% is fine, from a pure battery tech aspect, 80% is better unless you really need the 90%. Since Im working from home now, I charge to 70% and 4-5 days later again when I get down to ~30%.
Also, if you dont have a place to charge at home/work, and once per week supercharging is your only option, then you have to do what you have to do. It's certainly not the end of the world.
