Sure.

However, the method I mentioned can be done with zero extra server load if done correctly. I've done this before with other editors, and it definitely did not take a team 12 months to complete.

It is a full stack optimisation however, from UI all the way through the DB and the rest of the stack. Now that they're using only 10% load, there's plenty of room to breath.

Saving a draft of what someone may have spend hours typing into a crash prone browser is good UI practice regardless.
