5e encounter guidelines do feel that way, to me, but I ran 1e for a long time, and got used to encounter-design as more art than science. It's easy for me to make or adjust a 5e encounter on the fly. OTOH, when guidelines are fast/easy/consistent enough, the 'needless' extra work can be pretty trivial, and even a little helpful. For DM with less than 35 years of experience, though, they might feel a little more 'necessary,' and the extra work isn't needless - and just how much, how onerous, and how worthwhile that extra work is, can become a real issue.All I know is, detailed encounter guides are needless extra work for the DM, and the play experience is better if the DM just eyeballs it, and places monsters according to what makes sense, and not what he thinks would be an "Easy" , "moderate" or "hard" encounter for the party.
As far as the one style & play experience you prefer, sure, it doesn't require encounter guidelines. It's also not the only way to play the game.
