So you say each value...(are we talking about multiple values or values
with semicolon?). What are the most used values: unique or multiple? Why
don't we use multiple values more often?

Because it follows one tag-one value policy I supose. But I don't know why
in the wiki I read "avoid semicolons"...if it is the best way to manage
multiple values. https://wiki.openstreetmap.org/wiki/Multiple_values
<https://wiki.openstreetmap.org/wiki/Multiple_values> .Change the wiki to
encourage people to use multiple values.
*When (not) to use multiple valuesFor better or worse, a mapper's first
reaction to MV tags should be to avoid them. This is largely because many
data consumers do not handle MV tags well, either because they didn't
expect them or because handling them is complicated. As the OSM data model
doesn't directly support multiple values, they have been tacked-on with
various degrees of akwardness.*"

No. Did you do it about semicolons? What are the results?

Also I did not any scientific experiment. Did you do it with semicolons?
What are the results? It will be interesting to know it.
