Spanish has actually three levels of formality when addressing someone by name:
<First name>: Informal, casual conversation.
Don <First name>: More formal, conveys respect while still indicating some closeness.
Señor <Last name>: Most formal, normally used in writing.
Using only someone's last name is just plain weird. If you want to speak formally to someone just address them as "usted", it will get you the same goodwill without sounding off.
I agree it's more likely to be used by older generations but it's not uncommon to hear it around either, especially when addressing or refering to elders

Don it's very outdated unless you address a very important person.
Don is especially susceptible to huge regional differences. It's as GP described in Honduras and I think as you described in Spain.
