   Yes, it's about dub packages, not about subdirs. And yes, it's 
possible to split project to subpackages, it gives its benefits 
and structure code, but I hate the idea of doing this forcibly, 
just to fix compilation time. In addition, a typical large site 
is a large number of pages with diet templates, and even if you 
separate the pages from business logic, but this part itself is 
still very large and slow in compilation. I had to refuse diet 
rendering on the server and go to Vue+pug, which allowed to 
accelerate the development cycle when changes on the frontend 
from 2 minutes to instantly.

I believe that this situation is bad for D as a whole. The 
problem with large projects can be solved by splitting into 
subpackages, or with Scons, or with reggae, or manually writing 
the makefile, etc., etc., but the person who just started writing 
on D does not know all this. He simply does the project and with 
his growth discovers this problem. I think the modern programmer 
has the right to expect that the official build system will work 
well enough with a project of several thousand files.
