Shouldn't we need to load `swift55_hooks`?

Hello.

I am interested in compatibility of Swift Standard Library.

I noticed that runtime of swift 5.5 has loading override section name which is __swift54_hooks.

Shouldn't this be __swift55_hooks ?

This means that when swift 5.6 is released in the future,
we will not be able to specify different hooks for 5.4 and 5.5 runtimes when we modify the behavior of past runtime functions.

I checked differences in CompatibilityOverrideRuntime.def and found there is no changes from 5.4 to 5.5,
so it seems that same hooks can be specified for 5.5 as for 5.4.
Is that why we didn't rename the section?

However, further examination of changes for CompatibilityOverride.def (file renamed in 5.4) showed that there was also no changes from 5.1 to 5.2 and from 5.2 to 5.3.
Since the section names have changed between 5.2 and 5.3, has the policy changed?
