They are absolutely a bandaid for the politics of homeowners and their rule of housing supply. Homeowners can see themselves benefitting from ADUs, so they support them. Apartments, townhomes, etc. only weaken their market power, make homeowners think about traffic, etc. The politics of housing is completely broken because the incentives are broken, and so is the political discourse, which is dominated by creationist-level magical thinking that vacancies, or foreign buyers, or AirBNB, or "financialization" or literally anything could be the cause of the problem rather than a shortage of housing stock.
