My 2 Cents:
Like many have said, companies deliberately introduce products that are imperfect. With the Helix, which is pretty much a computer with some buttons/knobs/in-and-outs, it's all about the software. The software is not perfect. It will never be perfect. The Line 6 people are purposely milking it with gradual improvements... and/or things do get developed gradually over time. Sure, the Helix can have an amazing surfy reverb sound, but they are deliberately taking their time with it. Similarly, the EX "Freeze" pedal, they could have released it 4 years ago. Or how about the concept of a "Global Block" that people have been asking for for years. Not now, not yet... Maybe they'll introduce these in the next generation of the Helix.
Let's look at Apple, the first iPhone. It was fantastic, but the camera did not shoot videos, you could not switch between apps, you couldn't copy and paste! All those things could have been implemented from the get-go. However, Apple wanted to say "the new and improved, the best iOS ever..." etc. It took a few years until we could do copy-paste in iOS, while many phones from the early 2000s could do those things.
Having said that, the Helix is damn-near perfect for my needs. I keep tweaking my sounds and the more time I spend with it, the better my tones get. I'm glad I bit the bullet and switched over to the digital side. If it weren't for the Helix, I wouldn't have been able to record guitar during the quarantine.
Just this weekend, I finally dialed in the perfect surf "drip" reverb sound. I'm sure Line 6 could have included it as its own separate effect years ago. But anyway, here it is, if anybody's interested:
