[NTG-context] [luatex-fonts] +mkmk; +mark results in call to undefined onetimemessage()

Hi, in luatex-plain, the example below \font\grk="file:LinLibertine_R.otf:+mark;+mkmk;mode=node" at 14.4pt {\grk μῆνιν ἄειδε θεὰ Πηληϊάδεω Ἀχιλῆος\hfill\break οὐλομένην, ἣ μυρί' Ἀχαιοῖς ἄλγε' ἔθηκε} \bye triggers a call to onetimemessage() which is nil at the time when the upvalue is created. Can we have calls to fonts.loggers.onetimemessage() instead, so we can override that one with our own logger? On a related note, we would like to reduce verbosity. In luatex-basics-gen.lua, could we have: logs = logs or { new=dummyreporter, reporter=dummyreporter, messenger=dummyreporter, report=dummyfunction, } So we can provide our own “logs” table? Thanks Philipp
