I am referring to Italy.
Up to about one year ago we had only one type of cycle lane. These were by
law all "mandatory" in the sense that cyclists were obliged to use them,
and motorized traffic was supposed not be present on them, not even for
short stops. They are officilly called "pista ciclabile" (the same term
that is used for separate, stand-alone cycleways). They were tagged in OSM
as cycleway=lane or cycleway:left|right=lane, as the cycleway=mandatory tag
did not yet exist. There are roughly  5.5k of these in OSM in Italy.
One year ago the government created new cycle lanes, also called cycle
lanes in Italian. These correspond to the advisory lanes concpet in OSM
(only painted on the road, only week mandatory use by cyclists, and cars
con go on them, and even stop on them. So the need to be tagged differently
from the original cycle lanes. As it is out of question that we can retag
the older ones as mandatory in any automatic mode, we end up with an
ambigous tagging.
I had pointed that out when the key:cycleway:lane
<https://wiki.openstreetmap.org/wiki/Key:cycleway:lane> was discussed.
Too late now, I suppose.

If tagging conventions are not in presets and not properly documented in
the wiki, they are relatively useless.
Cycling infrastructure tagging is already a mess with what is in the wiki,
add to that the unfortunate cycleway:lane additions.

Yes the mess is limited to some countries. Italy is one of them, not helped
by the odd legal definitions (most prominently that the very frequently
used shared foot-cycle-ways are legally sidewalks, where bicycles are
tolerated, but pedestrians have priority, and which are not msandatory for
cyclists. But only a small percentsge of cyclists know that). And these
shared foot-cycle-ways are not in the wiki, not in the preset of iD. They
only are in JOSM.
