The usual suspects will say these are bland, unadventurous, etc. (and lacking some jokes!!) but they provide a reasonable basis for the next GE's manifesto. Nothing controversial, keep it simple and it's notably more ambitious than the current governments five pledges.
WRT to housing I'm sure their will be greater detail in the actual manifesto, just as there will be on defence, education, social security, et al.
Way too soon to be over specific on policy, best to keep the powder dry.
