for a weekly data set, the accessor $obsmicro returns the day instead of the week.

Yes, that is according to the spec (=expected).

Thanks for clarification, Sven.

Actually, thinking some more about it I'm not sure it really is documented (and perhaps not even explicitly intended). I'm also noticing that adding periodic dummies (in the GUI) and the seasonals() function in a weekly dataset work just fine, so in the background there is some week indicator.

I would have expected that for this frequency the "micro"-frequency should refer to the calendar week.
Given the periodicity 52 perhaps the "minor" frequency would make even more sense, thinking about a year:week structure.

Indeed, seems like I need to write a my own function for this ;-)

Here's an idea (relatively brute force):
open nysewk.gdt
list s = seasonals() # gives S1...S52
series obsweek = NA
loop i=1..$pd -q
  obsweek = (S$i == 1) ? i : obsweek
smpl full
