Sure Cubase could. Any DAW could. But remember the cheapened environment of radio since FCC deregulation in 1996 leading to cookie-cutter ownership of thousands of radio stations under 1 owner. There is more entry level positions today, and wages have definitely not kept up like it was prior to 1996 when adjusted for inflation. There are more student interns, some fresh off the streets hired to babysit 5 computers running 5 AM/FM voice-tracked stations, and always “by the way here is the copy to get these 10 spots completed.” You need a simple uncluttered seamless program program to accomplish relatively narrow audio objectives. There are a lot of programs more intuitive for a beginner than Cubase.
Now I’m sure I’m going to hear about all the USA radio stations using Cubase. 
A DAW with score, all sorts of deep midi not to mention logical editor, is just overkill and distraction for most local radio station production IMO.
Production for major radio markets, and especially regional/national I would guess it’s just as you mentioned. In that scenario, why not use lanes? Regardless of music or voice, I would think once you get a workflow down,it could be very useful. Have you found drawbacks? I totally agree that best practice depends on how glued you are to your favorite tool. Emphasis on the user and comfort with the tool, and with my limited use of lanes, I think that is possible.
Side note: 25 years ago in the 149th largest radio market in the USA
, we had 2 production rooms.
“A” studio had a 16-track tape machine with a 11 foot long 32 track analog board including an Alesis SR 16 drum machine, Ensoniq EPS sampler, vocal booth, and a top-of-the-line CD Hollywood production library that was the envy of everyone in town.
“B” studio had the normal stuff found in any production room…at the time 2 new DAT’s, and the standard 4-track Otaris with the great splicers, and a standard radio mixing board.
I’m guessing it was a tax write-off for the radio station owner which was the phone company, but studio “A” never got used…ever. However it was fun to play around in and pretend I’m Trevor Horn.
