[Dev-luatex] Missing opentype font entries in fls file

[Linas Stonys]

Hi,
I've noticed that there's no INPUT entries of any modern font (otf, ttf)
in .fls file with TL2018.

VERSION:
This is LuaTeX, Version 1.07.0 (TeX Live 2018/W32TeX) (format=lualatex
2018.6.5) 2 OCT 2018 15:59


EXAMPLE - MYRIAD.TTF I put in local directory:
\documentclass{article}
\usepackage{fontspec}
\setmainfont{lmroman10-regular.otf}
\newfontfamily\myrfamily{MYRIAD.TTF}

\begin{document}
Abc def ghi {\myrfamily used myriad}
\end{document}

in the log file I see:
<./MYRIAD.TTF><d:/texroot/2018/texmf-dist/fonts/opentype/public/lm/lmroman10-regular.otf>


TL2016 with this small example acts the same but with larger file and
"home made" class file I see INPUT lines but only with TL2016:

INPUT
C:/Users/lstonys/.texlive2016/texmf-vtex/luatex-cache/generic/fonts/otl/lmroman10-regular.luc
INPUT
d:/texroot/2016/texmf-dist/fonts/opentype/public/lm/lmroman10-regular.otf
INPUT
C:/Users/lstonys/.texlive2016/texmf-vtex/luatexja/extra_lmroman10-regular.luc
...
INPUT
C:/Users/lstonys/.texlive2016/texmf-vtex/luatex-cache/generic/fonts/otl/myriad.luc
INPUT ./MYRIAD.TTF
INPUT C:/Users/lstonys/.texlive2016/texmf-vtex/luatexja/extra_myriad.luc


Could INPUT lines with used fonts appear in future texlive versions?
Inputs from fls I use for making proper back up of project used files.
