I think that very little software is hurt by supporting multiple platforms -- usually the software benefits from exposure to a different set of assumptions and can be made more robust for when the preferred set of systems changes in the future. Does your software compile for WebAssembly today ? If it it also compiles for MINIX, it probably already supported WebAssembly as soon as a compiler backend existed without you having to make any changes.
