Nobody wants to take SRO's because it is literally impossible to change the situation once the person is in there. The Rockaways have a problem with this and the solution from landlords is to literally let the entire structure fall apart due to the inability to evict tenants.

I'm not saying it's right but you'd have a higher chance getting brand new housing projects built than getting any landlords on board with willingly allowing SROs in any of their properties.
