Switching to D7 before biometrics for GV

[cj807 (Chris J)]

I think it’s long been conventional wisdom on this site that you can’t apply for both at the same time, or at least that’s SEF’s position. See e.g. the last post here:

Getting D-7 whilst waiting for Golden Visa

I have heard that getting a D7 is much quicker than GV. Our lawyers have told us that starting a second application whilst waiting for the GV is not a good idea. But we are at our wits end here, with no end in sight on the GV. Can anyone comment on if they’ve done this? What are the real dangers? Thank you!
