Not that I’m aware of.  biblatex tries hard to keep backward 
compatibility, especially with the BibTeX entry *format*.  So I’d be 
surprised if that was the case. (Not so with a field with text, 
e.g. `month = jan` is indeed different from `month = "jan"`).  I’ve been 
active a number of years on TeX.SX with the biblatex and biber tags, and 
I don’t recall a case of missing braces in dates producing issues.  Of 
course, it is hard to remember such things, so before I wrote I had done 
some (light) testing on a file with different cases and built it 
successfully with `latex -> biber -> latex` with a current TeX 
Live. (That’s why you got "Author2019c" as an example).  Anyway, since 
you asked, I took a look at the file "biblatex-examples.bib", which 
ships with biblatex and which, as far as I know, is the one used for 
testing it, entries such as:

   }

And there is plenty more of examples of numeric fields without braces or 
quotes there.

Regarding latexmk, I’m not a regular user of it.  But, as far as I know, 
it is not a proper TeX “engine”, it is a build automation tool which 
wraps around the usual ones.  So I see no reason why it should make a 
difference.

Best regards,
Gustavo Barros.
