Not necessarily, because <Composers> will be formatted as
Person 1; Person 2; Person 3
while my use case for "Display Composers" is Person 1, Person 2 and Person 3.
I am doing: Composer1, Composer2, Composer3 for <Composer>
and Composer1; Composer2; Composer3 for <Composers>
So the first one can be used for displaying purposes, and the second one for 'database' purposes.
Which is exactly the same as how I am using <Album Artist> vs. <Album Artists>
To dive in a little bit deeper:
For me <Composer> can also look like:
Wolfgang Amadeus Mozart (Franz Xaver Süßmayr)
if there is a 'main' composer and another one that has done edits or completions.
I also have <Sort composer> that only contains the last names:
Mozart (Süßmayr)
In my case all the heavy lifting is done by Picard (scripts) that produces these variations of 'composer' tags exactly to my liking.
Pretty much all MusicBee has to do is read them.
(and using some fairly simple virtual tags on them)
