There are actually a lot of supports that scale very well but not damage-wise. Janna, Lulu, Nami, Soraka, Sona, Bard, probably even more. Those are all dedicated to utility, and their utility, you guessed it, scales with AP.

Nami for example has AP ratios on her passive (to increase the MS), on her W (to increase heal and heal/damage-amplification), and on her E (to increase the slow percentage).

Janna has an AP scaling on her W (to increase her own MS and the slow percentage), on her E (to increase the shield and the AD it grants), and on her R (to increase the heal).

Building a mixture of support items (especially Zeke's Harbinger) and AP items (Rabadon's Deathcap) helps her out a lot and hitting 200 AP is almost a must-do.

Supports scale with items, but instead of their damage ramping up, their utility grows more impactful.

And for the 15% more bonus health: Support items often grand low amounts of health, unlike pure tank items, and instead grant higher utility. That way it helps tank supports, especially Taric, Braum, Tahm Kench, and Nautilus who all scale with health, to stay tanky enough in the late game.
