Counting all the changesets in the public hg lDebug repo since the first revision on 2010-10-24 we're at changeset 5997 now. Have some statistics about the size of the sources:
These counts were generated using the cntlines program. The lDebug revisions are as linked above. The FreeDOS Debug/X revision is version 1.13 from 2008-02-27, which was the last revision that had NASM source texts. That fact led to the fork that would eventually become lDebug.

The next version of FreeDOS Debug/X was version 1.14 on 2009-01-12, which switched the source text to use JWasm rather than NASM.
Prepared a small googlesheet with some charts. Not satisfied with the options their app provides but what's there is already neat: https://docs.google.com/spreadsheets/u/0/d/1cL3TrSkh1L34LTBR8xNi9XHTY76n7k9AfJ2DAisiMqQ/htmlview
