SVI/HSRP Configuration confusion

Why is it that everyone (every network engineer I have met) configures HSRP on the vlan interfaces on a distribution switch as opposed to other virtual interfaces such as loopbacks etc. All that is listed as supported is Routed port's, SVI's, and Etherchannel port channel in Layer 3 mode.

I guess I have just never seen a use case and was wondering if one could be provided.

I was looking over the cisco documentation and the examples they give have it listed on an actual physical interface, which confused the hell out of me.

Example: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12-2_55_se/configuration/guide/3750xscg/swhsrp.html#10033
