@dolik-rce unfortunately there are so many changes to the general ctags infrastructure it needs one of the (few) people who know ctags to look at it, the rest of us would spend so much time understanding the basic ctags operation that we simply don't have the time to look at it.
Also I personally don't understand why #2584 changes only 20 files for both tags parsing and a lexer and you change 57 files for just tag parsing?
