TRFs are fine. The high-end German manufacturer Körting was turning them out as late as 1939 - complete with diode detection and neon tuning indicators (e.g. the
Novum 40, of which I have an example). Some sets were switchable TRF/superhet - the argument was that for local quality reception a TRF didn't suffer from conversion noise in the way a superhet did and you could also get a wider bandwidth.
In the UK many bespoke manufacturers of high-end sets also did the same - Haynes for one, Expert another.
