I'm not actually a huge fan of the redesigned signs. It seems like it would be really hard to make work for even slightly complex cases -- alternate side on Mondays during the Fall for example, or 2-hour parking during the day except for residents.
Also, like most unsolicited unofficial redesigns, it ignores real-world constraints. How much does it cost to produce these very specific signs vs combining modular and reusable generic signs?

Probably less than the cost of a single parking ticket.
As for your corner cases, there are some signs depicted with text at the bottom which can cover those scenarios. Not perfect, but I think it's a step up from what people have to deal with today.

I really doubt that, but my point is that none of us know. Design is a lot easier when you're ignorant of any cost or logistical constraints.

I guess it's better, but it seems like greatly more complexity in creating and managing signs for only a little benefit. At least around me those aren't corner cases: pretty much every sign would have one or more additional restrictions or exceptions. In front of my house it's two-hour parking Monday through Saturday except for residents, and no parking on Mondays during the Fall. I think that's pretty typical for DC.
