Yes. If something goes wrong with your return line, all your pool equipment goes down because you can't get water back to the pool with just one return line. Should you have multiple individual return lines, if one of the return lines goes wrong, you still have 1 or 2 other lines functioning so you can keep your pool in working order while you diagnose and fix the line with the issue. It's one thing to buy a house with a pool that has all the returns or skimmers tied to one line. If you're building it from scratch, why not give yourself the flexibility with individual lines. It'll double your plumbing work now, but you'll be glad if any of the lines ever has an issue plus as noted above you can control the flow.
I just built my pool in 2022. I have 2 skimmers and 4 returns; all are plumbed with individual lines.
and kudos to you, doing an OB as a single mom of an 8 year old. Congrats! Hope you had an amazing Mother's Day!
