Custom-page-size and/or shrink memory

[lum1n0us]

WebAssembly/spec#1753 (comment)

The custom-page-size feature is a standard proposal that overlaps with the current shrink_memory implementation based on heap_base in wasm_loader.

The unresolved question is whether we should retain both features or just maintain one

Given that shrinking memory is not a standard operation, yet there is consistently a need to reduce memory usage, should we make it controllable and/or configurable? For instance, by using a compilation option and/or a command line option.

it makes sense.

while custom-page-sizes might be able to replace it in future, it's far from ready today.

#4008 will fix it
