It's actually encouraged in some cases where the implicit tag is not consumable by automated system (such as the "none" default for turn:lanes tends to be ambiguous between "you can't turn from this lane" and "you can't use this lane" and "there's an implicit but unspecified implication that isn't painted on the ground"), or access defaults (such as in the US where bicycle=* and foot=* varies a lot on highway=motorway)
