I find it odd that inaction, incapability or incompetence of local sign
installers is a worry for a database of geographical facts, which OSM is.
Some roads are hundreds of miles long, at what interval does it need to
be signed for it to be considered signed. Beginning and end? Every 100 km?
Some streets have signs that are now obscured by trees and bushes.
"On the ground" rule is a rule of thumb, not the entirety of factual
truth. People similarly being lax in making sure their homes conform to
local rules about address visibility (huge pet peeve of mine since being
a paper boy in the 1980s) should not hinder us in giving their homes the
proper address in our database of facts.
If you wish to use on the ground as the only rule then we can just
forget about the whole thing - defeated by inaction of people that
should be putting up signs and maintaining them.
As for the name inflation, there is no such thing. Illegal imports maybe
but name inflation as a problem does not exist. Any talk of "too much
data" by adding an extra name field to a node is defeated soundly by any
3d mapping entity. I've looked at some of the 3D stuff done and it blows
my mind how detailed and cool it is, then when I peek at the code behind
it I admit defeat in trying to understand it at a glance as it is an
intricate series of relations upon relations. A simpler example is Stade
de France, fantastic stadium - was there myself at 1998 World Cup.
Data bloat can happen, Wikidata is too fragile, we need our own store of
data (POI extra details, names, translations etc) that can exchange
material with Wikidata but is under full OSMF control - and not
controlled by notability deletionists. In 5 years time would we be
arguing about bloat in OSMData as someone suddenly purges some section
from it?

That's really neat. How do you know wether a street is signposted or
not ? I don't know of any tag that gives that info.
there are ~600 visible_name
37000 unsigned_ref
518 unsigned
400 signed
161 name:signed
124 name:sign
86 ref:signed
48 unsigned_name
47 ref:unsigned
16 name:signposted
I haven't checked on which kind of objects or which do not refer to highways or
names
Very likely I also missed some variants
It seems that for names nobody cares to say whether they are signposted or not
(or maybe only when the sign is different from the actual name), while for ref
it seems common practice(?) to use unsigned_ref
