Yes, the government subsidies for home batteries specifically are a very poorly targeted handout. Unfortunately splashy policies like this are classic vote buying measures, even if economically they don't make much sense

- home batteries cost more

- homeowners buying batteries are already pretty well off on average

- a large portion of the population (renters) is excluded from the policy.

- prices are falling anyway so the subsidy is just a waste of tax dollars, arguably

- grid scale batteries are more cost effective and benefit everyone via cheap prices broadly, instead of specific homeowners.

Etc. but pork barreling be pork barreling.
