I think it's more about the cell towers being cut at the same time as their local area.
Where it's easy to anticipate that hospitals/police stations/fire birgades will need a special connection to the grid, it probably was harder 20 years ago to realise the numerous new cell towers also needed to be put on a separate connection.
So they'll get cut at the same time as the companies and the houses in the local area.
In France, the talks about the rolling blackouts were acompanied by assurances that private homes wouldn't be affected, only industries.
So they should have some kind of ability to target at least a kind of user. I don't know if cell towers qualify as industry or their own, separate kind.
There's also the fact that there has been a massive rollout of connected meters, so, at least in theory, they could target individual homes for the blackouts (I'm not saying that would be useful in any way).
I don't know if other kinds of endpoints have similar kinds of meters, but they could.

Industrial power is easier to separate because it is almost always a separate grid region. There aren’t many houses built up against your local steel mill or refinery.
Cell towers are collocated with residential areas because that’s where the users are. The power for homes and cell towers comes from the same source.
