Customer is king, when one needs them, it is the one trying to make money that needs to accommodate.

When not, others will.

Customer is king indeed but why they expect/want to use latest boost if their infra is old? Use the latest version your infra supports, simple!

[LaLaLand122]

The customer

- "Wants" "stable", i.e. the default gcc

- Doesn't care what Boost version is used

- Pays the developer

The developer

- Wants the latest toolchain

- Wants the latest Boost

- Makes money

The developer

- Accepts using an old compiler because Boost keeps compatibility with it

- Does not pay Boost developers for it

There is no single entity that wants old compiler (other than to satisfy others) and new Boost.
