Then it needs to be made standard. Without that, or an equivalent solution, garbage collected languages will remain unusable in constrained environments.
I think the real impediment isn't related to garbage collection, but it's just ecosystem inertia and industry knowledge inertia--the same forces that inhibit Rust adoption or C++ adoption or Ada adoption. Does that seem reasonable, or am I misunderstanding? What do you think?
C and C++ start out so unsafe, I can hardly use them on substantial projects without sanitisers now. Sanitisers need to be made standard so I can use them everywhere.
Garbage collected languages start out with unpredictable memory usage, making them unusable on constrained environments without the relevant memory analysers (static or dynamic). Such tools need to be made standard so garbage collection may be an option on more platforms.
