That’s fine, I just like to fill in a dead space like that with concrete if the home is on a slab.
The idea is to put the flange at the correct height. Your spacer does that. That’s what I do on wood construction.
On concrete I use the concrete I linked to you.,
I would use the anchor cement to fill in rather than silicone.
I’ve been doing it this way for 30 yrs and it works perfectly and lasts.
