While I acknowledge that most of these plants are worse (Though your logic for Aloe and Hypno-shroom I find questionable), it boils down to personal taste. I just don't like how Magnifying Grass works. I mean, I find it hard to see 50 sun on 27.5 damage to be a worthy investment when I can do so much more with 50 sun (Like, say, Primal Potato Mine, as you mentioned.). Yeah, I know, they have a pretty bad recharge, but they still do more damage for what they cost. I just feel like I'm wasting 50 sun when I fire a projectile that can't even kill a conehead.

And one thing you forgot to take into consideration for your choices is plant food effects:


 * Yes, Shadow-shroom is pretty bad on its own, and using PPM or Squash is a far better idea, but if you give that sucker some lunch, then it poisons every zombie on the lawn. Almost nothing short of Gargs will survive.
 * The Hypno-shroom, honestly, isn't as useless as you make it out to be. Sure, Caulipower can do the same infinitely, but it does so quite slowly, and may (By that, I mean likely will) not hypnotize the zombie you want to. Plus, its PFE is awful, flicking away a couple of zombies in a short range. Hypno-shroom, on the other hand, turns the zombie that eats it into a Gargantuar. And if you've played the game for any amount of time, you know Gargs are formidable. It's amazing for stalling and destroying zombies, even moreso than Stallia.
 * Chomper is a relatively useless plant. However, his PFE is one of the very best in the game. Sure, he eats only a few zombies, but what really sells it is the blowback. Having a boosted Chomper effectively gives you a makeshift Hurrikale with a fast recharge. Toadstool's is nowhere near as useful, only eating 4 zombies in a limited range.
 * You've already mentioned Spring Blover. Though on Pirate Seas, you don't even need Blover most of the time for the strategy to work.
 * Assuming the stupid glitch is fixed, Sun Bean also has a good PFE, where even a basic zombie gives a ton of sun. If a Mecha-cone eats it, it gives over 1000 sun.
 * And though Aloe doesn't have a good PFE, he has great use with certain plants, such as Chard Guard, Garlic, and Sweet Potato.

What does Magnifying Grass get? A laser beam that barely pulls the bucket off of a buckethead.

And lastly, you mentioned some plants have a niche use. A plant with a niche use can still be considered useful. Those plants' niche uses are better than Magnifying Grass', in my opinion.

TL;DR: It boils down to opinions. Magnifying Grass isn't necessarily bad, it just hits every aspect I don't like about a plant, making it ultimately the plant I like the least.
