It's very productive, because abusing terms like "WFH" will be the technique that companies use to try and get through this without giving up anything. If you thought you were going to be "working from home" and discovered that your boss had the option to demand a commute from you at will on short notice, you would probably feel like you'd been tricked, no? Or if you landed that dream WFH job only to discover that it required you be X miles from Y expensive city, you would probably have some questions about what exactly they meant by "work from home".
Personally, I'd call the environment OP described above as semi-remote or "Flexible Working Arrangements", although I'm sure there are other terms that would suffice.

Not for me, but that's fine I guess. But it's very important that everyone be clear about what this is, and it's not WFH. If the expectation is that you'll commute regularly or on the demand of your boss (ew), then that's not a WFH job. Come up with a new name for it if you want, but it does not meet the social expectation of what "WFH" means.
Unrelated to the terminology, I find this intermediate proposition utterly perplexing. So I have to live within reasonable commute range for the 2-3x times I commute per week, and I have to pay higher per foot cost if I want to work from my home? You do you, but I find this to be the worst of both worlds; I'd rather have a short commute to an office all the time, or no commute and more personal space.
(Excepting of course the “I have a dentist appointment in the other direction, I’m going to WFH for that.” But even my non-remote jobs have offered one-off remote days for logistical reasons for years, so I implicitly exclude that from such discussions).
