You might find this a stumbling point for adoption. My first thought is this could be a good tool for me to use, but how can I send a design to someone else to get feedback on if I’m not going to expect them to also also learn how to use this or how can I get my design manufactured if the tools can’t export out the, normally very visual, layout files.
I do think that is fair. The reason that we don't have a visualizer is not that we don't want one, but rather that the value to effort ratio is quite low (and really because the effort is high, not because of low value). I'm sure we'll get there at some point. But at the moment there are more pressing issues for the people who are ok dealing with no visualization (like typing, language server, equations etc...).
I’d definitely consider not letting some basic visual schematic outputs fall too far down the priority list.
A lot of existing EE is basically just the visual diagrams and a lot of existing EE people will expect the tools to give them the visual diagrams they work with somehow… like even just including the compiled schematic as an SVG in with the compiled outputs of netlist, gerber, etc… something that other software can be used to convert to PDF without extra complexity in your tool and can be used to interoperable with the existing talent pool of EE people who have not just no idea how to use your tool… but know how to read typical style circuit diagrams.
