[Dev-luatex] require doesn't get recorded

executing \IfFileExists{d:/texroot/2019/texmf-dist/fonts/opentype/public/lm/lmroman10-bold.otf}{}{}
writes an entry to .fls like:
INPUT d:/texroot/2019/texmf-dist/fonts/opentype/public/lm/lmroman10-bold.otf

that's what this code does for every used opentype font. I tried offered fio.recordfilename(fdata.filename)
but did not see any difference in .fls
