latex or l3 changes in 2020: starting to request tcrm fonts?

[Norbert Preining]

Hi all,

it seems that one of the recent changes in some of the latex/l3 packages has
triggered a new dependency (implicit): When compiling a document without
collection-fontsrecommended installed, it still requests the tcrm fonts:
	This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/Debian) (preloaded format=latex)
	 restricted \write18 enabled.
	entering extended mode
	(./main.tex
	LaTeX2e <2020-02-02> patch level 1
	L3 programming layer <2020-02-08>
	(/usr/share/texlive/texmf-dist/tex/latex/base/article.cls
	Document Class: article 2019/12/20 v1.4l Standard LaTeX document class
	(/usr/share/texlive/texmf-dist/tex/latex/base/size12.clo))
	(/usr/share/texlive/texmf-dist/tex/latex/base/inputenc.sty)
	(/usr/share/texlive/texmf-dist/tex/latex/preprint/fullpage.sty)
	(/usr/share/texmf/tex/latex/misc/ocamlweb.sty)
	(/usr/share/texlive/texmf-dist/tex/latex/l3backend/l3backend-dvips.def)
	kpathsea: Running mktextfm tcrm1200
	/usr/share/texlive/texmf-dist/web2c/mktexnam: Could not map source abbreviation  for tcrm1200.
	/usr/share/texlive/texmf-dist/web2c/mktexnam: Need to update ?
	mktextfm: Running mf-nowin -progname=mf \mode:=ljfour; mag:=1; nonstopmode; input tcrm1200

This is by itself not a problem, only that it is new and breaks building
of some Debian packages that didn't require collection-fontsrecommended
till now, and suddently need them.

Is this a known "feature"/issue?

Best

Norbert
