I kind of wonder if this can be gamed, by closing train stations or moving bus stops, or bus lines.

There's another way it will be gamed without having to close or move anything:

> (e) “High-frequency commuter rail” means a commuter rail service operating a total of at least 48 trains per day across both directions, > (r) “Very high frequency commuter rail” means a commuter rail service with a total of at least 72 trains per day across both directions

I bet some schedules will be changed to fall below these requirements.

edit: I should preface, I am very pro dense housing.

Probably, but there is a lot of money on the table for developers and so I think capitalism will be aligned with denser housing for a bit of time. Developers with deep pockets aren't interested in maintaining property values for single family homes, they will want to buy up land cheap and build station/commercial complexes for dense housing to build up around.

That's my view anyway. The upside of dense living is the affordability for individuals, one of the downsides is that it can favour big corporate developers. Shared ownership structures are really important to help mitigate that for residential developments.

In a society that works together this can be symbiotic, and really efficient way to build. For a country that lets the rich eat the poor, there is potential for exploitive scenarios to arise without the right regulation in place.
