while the EN wiki page https://wiki.openstreetmap.org/wiki/Key:tracktype
  does not explicitly exclude it but "only" strongly suggests it by
telling "Usually a paved surface (called also  Sealed road)" for grade1
and "Usually an unpaved track with surface of gravel", the DE wiki page
https://wiki.openstreetmap.org/wiki/DE:Key:tracktype tells (translated
by me) "waterproof surface" and thus explicitly excludes the combination.

> Please allow me to add that what I'll call grade1 which ISN'T truly paved (or once was), but is essentially surface=compacted, is a distinctly different kind of road when it is wet, muddy or actively raining (at least for such tracks/roads around here).  These become pretty slick and even "iffy" to drive upon (especially with > about 3% or 4% slope)

Exactly this is one major reason why I consider most surface=compacted
to not not qualify for tracktype=grade1.

Best regards,
Georg
