I have no control over what the backend does, but if it generates control variables for them (emulated tls), then __get_address would incur a small heap cost when first retrieved. If the cost is too much (ie: there is no heap), then we should be able to stop emutls from kicking in by preventing the D frontend from returning true on isThreadLocal calls.
