“Supporting the status quo” is literally what conservatism is about, no?

Not when it attempts to violently overthrow the government, no. Liberal=change and Conservative=preserve status quo is outdated and no longer true in most cases/places. e.g. some say that Brexit was quite a "change" for the UK? But in any case it was most definitely not preserving the present status quo.

Mostly conservatism tries to recreate things from ~30 years ago as a nostalgic and optimistic hope that returning to the past will help overcome the current badness, e.g. as a method of combating inflation.

Except on top of it all is the difference between what is said vs. done, e.g. to return to the past economic success in the USA we'd have to increase the top marginal tax rate to 90%, but instead conservatives lowered taxes on the wealthy still further. "Conservatism" is often only the line that the ~~car salesmen~~ politicians sell, same as "Liberalism", for someone to get themselves into power.
