Use ISP's only for exits. Or you want "fun".
Some run exits from home because they have prepared in advance for, and do not mind, or simply enjoy, such free[dom] "fun", and wish to make a point and or cases. They could be considered activists.
If not prepared, or in jurisdictions that do not offer, at minimum, legal exemption immunity to operators for traffic passed as a "carrier / ISP", of course home exits would not be much wise.
Operators could easily make a wiki list of extra preparations for home exits to make. Other than a few items, they'll be similar to well prepared hoster exits.
