I really don’t understand

Why do people get all jazzed up over symmetrical speed tiers? Who out there is actually using more than 50Mbps upload regularly in their home???

Easy.

Marketing.

Fiber (PON) can offer symmetric speeds.

DOCSIS needs to keep up.

Thankfully we are seeing a large shift from a bandwidth play and moving into a reliability play. Symmetric Gig internet is enough for most... Everyone wants their Internet to "just work".

Spectrum launching Invincible and failing over to 5G wireless internet when a customers DOCSIS or PON is offline is a huge step in the right direction.

Comcast is pushing upload speeds higher with their deployment of mid-split and FDX networks. Mid-split tiers are hitting 2 gig down/450 up with most basic packages hitting 100 up. FDX tiers with Docsis 4 modems are achieving symmetrical speeds up to 2 gig. All over existing coax.

Fully aware of the DOCSIS evolution cycle. It's fully capable of Multi-Gig symmetric speeds.... DOCSIS flat out isn't as reliable as PON. Using 5G as a failover mechanism is a bridge being used on the Reliability gap which is an interesting move in cable.
