I think not having certain things baked into the system can also be good since it lets you add something that suits what you need at the moment. A couple of sessions ago, I was going to be running a battle between a horde of orcs, goblins, hobgoblins, and ogres and the PCs town with their own orc allies and so I needed a mass combat system for the game.
I looked around at a number of systems including mass battle system rules from BECMI, strongholds and followers, ACKs, birthright, and even the old UA mass combat rules. In the end I created my own system kind of based on BECMI. The player's side had an attack bonus based on their own resources and tactics, and the enemy set a DC of 10 + the same numbers as the attack bonus. Then I had the players in the midst of battle fighting targets of opportunity, depending on how well they did, I'd have one of them roll for their army and maybe apply advantage or disadvantage. If they did well, some other targets of opportunity were swept from the board (I chose the targets removed but I think if I did this again I'd have the players choose) and this would impact the end of the battle.
It worked well, I didn't need to bring in any advanced rules for controlling units and essentially making the PCs disappear within the grand melee. Had a mass combat system been baked in, it likely would have been expected to use it and I may have never even considered something else. This was also something I only figured out on the week leading up to the session, I'd been trying to think of a decent system for weeks since I knew this was going to happen but nothing really fit with what I wanted.
