Why don't the usual suspects (Topping, Sabaj, Smsl, Loxije etc) touch the dsp market?

The question is serious, and is aimed at anyone with sensible hypotheses.
In a market so saturated with dacs of all kinds, where a new photocopied dac comes out every month, all with the same functions, all with the same characteristics, how is it possible that none of the low-cost Chinese companies have set their sights on this market?
A product like the topping E50, but with dsp capability, would probably be bought in bulk by anyone looking for a room corrected dac.
Currently anyone who wants this function integrated in the dac is oriented towards minidsp flex, which is the only product that is quite cheap, complete and with good performance.
Lack of technical ability? Lack of ability to develop matched software? Wouldn't the number of potential interested users justify the development?

Adding a 10-band PEQ to a DAC - What is holding manufacturers back?

Sony could do a 3-band one in 1989. What is it that seems to make a proper stereo DAC with just 7 more bands too much to ask for in 2022? No software interface required, a simple screen and a couple of front panel controls would do. Even be preferred actually. Is it too difficult? Too niche...

DSP requires writing software and designing GUIs. Plus maintaining that software across multiple OSs.
Topping, Sabaj etc. probably just aren't ready yet to take that step.

If you were one of these suspects and your proposition included external software - would you do it? I know I wouldn't. Even Neumann struggles to get that part right.

I do see viability in a fully self-contained unit though. After more than 20 years, Behringer's DEQ2496 is still a perfectly valid option when you can stay in the digital domain. Would it have had a 2023 quality DAC section, volume control, and look a bit neater, I'd get one for twice its price today.

Because there is Neutron Player,
and the smartphone is the perfect place for a DSP.

Interesting. How would I use a smartphone to DSP my TV sound?
