From what I can tell, HP's non-invasive BIOS recovery options are very model-dependent, and even models which do allegedly support recovery reportedly refuse to boot into recovery mode for some folks.

But yes, Dell is the outlier that has me saying “likely” instead of “definitely” above; they've had orders of magnitude more time and money than Framework has to throw at BIOS development, and it shows. I agree with you that Framework should be making a priority of getting their BIOSes to that level; I'm also willing to extend them some grace given the company's age and resources.
