I generally like the idea of a hint section. However, I think it makes sense to reduce the granularity of the hints to make simple, clear signals. E.g. one proposal that has been discussed in various offline conversations is a "hint section" to specify per-function hot/cold/startup hints that basically tell an engine which tier to use for which function and whether each function is needed for "fast startup" or not.
use HOT as compiler directives and profile hints for efficient prioritisation.
flags: first bits should indicate { start/stop directive, linear sequence, iterator loop, parallel, parallel^, thread synch, (calls function), and optimisation profile (standard pattern)} float priority: 1.0f typical, sorted by compiler id: <></>
optional variable / register declarations
Also wise to include numeric scope for higher efficiency processing of fixed bit scope, io profile for gl and audio/video, hints on endpoint optimisation (pixel buffer, audio, webgl, etc.)
