It’s better to understand the options available, so you can decide for yourself when it’s best to use them or not. They exist for a reason – if they weren’t useful at least sometimes, the developers wouldn’t have spent their time implementing the feature!
You may have picked up a sense of resistance from other forum posters, if those posters wanted to encourage awareness of less manual options available that other notation softwares might not offer or not as elegantly as Dorico: like the note spacing and vertical spacing options, which are pretty powerful and well worth getting familiar with.
This is due to the different amount of horizontal space required when the notes are beamed together vs not beamed. Granted, the difference is very small, but in a system as close to being 100% full as in your project, that can be the tipping factor.
