I think this may be it. Its certainly what I would like to see. Of all the many cool things about Tesla, the supercharging network build-speed has to be the most underwhelming one. There are SO MANY people who say they cannot ever buy an EV because there is no place to charge it. They do have a point. Not everyone (especially in cities) has a nice allocated space in a driveway to home charge.
Perhaps the supercharger rollout is going to become supercharger + destination + homecharger rollout. In the UK, there are a lot of 'lamp-post chargers', but not enough, not even vaguely enough.
I do think Elon might be frustrated because the process of getting grid connections for high demand electrical installations like superchargers is absolutely torturous, almost everywhere in the western world. I'm not sure this is easily fixed. Hardly any locations have enough space for solar to make a dent in the power requirements. Solar canopies are basically window dressing for a supercharger.
Its may here, and my 10 solar panels generated 20kw of power today. Enough to fill a single model Y to 25%. In one day. And thats in Spring, not winter.
Superchargers may be the one thing that Elon finds out simply cannot be done 'china-fast' outside of China. I'm glad he is at least focused now on that part f the business though, (and Tesla in general).
Hearty agreement with your "cannot be done 'china-fast' outside of China" comment. There are some places (e.g. San Francisco) with onerous
bureaucracy for electrical permitting, together with utility (in our case PG&E) foot-dragging, so new Supercharger installations can take years.
In one case a location popped up with 72 kW "urban chargers" which are already obsolete ... As I mentioned on X to the comment
about a long-desired site in Hungary, "This is not controllable by Tesla, and Musk cannot dictate by fiat to other agencies as he can for Tesla."
Towards "supercharger + destination + home charger" rollout you mention, as an apartment dweller (though I co-own a home elsewhere)
I'd be happy with a grounded 3-prong 120V plug in the garage space, with only a two-wire lightbulb/socket switch there.
(The bldg is circa 1942 controlled by fuses and no circuit-breaker panel.)
There does seem to be a company dedicated to getting 120/240V landlord-metered outlets into multi-unit apartments --
a co-founder is an ex-Tesla engineer:
Orange designs and creates our hardware and software platform for electric vehicle charging to reduce the installation and management costs of electric vehicle charging at multi-unit properties.

They try to work with local electricians and realize that 120V is sufficient for many places since 4-5 miles/per hour adds
up overnight. You'd think that building owners might want to make money, but try that in rent-controlled San Francisco, where if
infrastructure costs even a nickel to install they wouldn't even try if they'd have to pull permits. I could get an electrician to put
in a GFCI outlet with no conduit or "panel" work, but I hear that the Tesla mobile plug won't work with ersatz grounding. End of rant.
