Not really.
There has been a long tradition of arrays down to
ILLIAC IV. They had big CPUs ( ILLIAC, Transputer ) and
small "CPUs"/PEs like CLIP4 and DAP. The later were
actully only SIMD-arrays, no independent CPUs. But
they are somewhat comparable to the crippled GA144.
The DAP was arguably commercially viable, as it was
still around in the 80ies. It used a fat SRAM early on
and "a variant of Fortan because thats what the
customers wants" to paraphrase them. So no
Color-Forth, no Spin-language, no Occam.
The CLIP group and everyone else soon too came to the
conclusion that they needed more RAM per PE too.
The Martin Marietta GAPP had even a odd Forth
connection: Ting used a NC4000 as I/O-processor.
There is a vast amount of literature out there
about these machines, how they evolved, what applications
were viable. Guess computer cowboy Moore isn't a reader.
Key problem: these machines were and are almost
exclusively for the "government projects" market.
The real computer cowboy is Chip Gracey because
his chip you can buy at digikey and ebay. Usable
for the hobbyist today, can slowly penetrate to industry.

That world doesn't buy from a company like GA. If they had any
credibility there they would get venture capital.
Hobbyists accept GA, small industry too. If you run small
projects using exotic chips isnt much risk. But a lot of projects
die at the breadboard stage. Not everyone has the equipment
to get BGAs and similar stuff in and out of boards.
Most users wouldn't mind if the "DIL40" is a FR4 carrier board
with a small LCN/BGA and capacitors on it that plugs in a DIL40
socket. Yes its more expensive, but it are boutique chips anyway.

As far as i remember there was an evolution from smallish single
CPUs MuP21 ( Ting ), F21 ( Jeff Fox ) that worked on external memory.
And were in no way competitive with controllers with integrated
memory from industry. So that was a dead end.
The F18 CPU was scaled down further to exclusively use SRAM on chip.
And a very rudimentary 4-way interface was patched on so these
can form an array. And thats it. There were never any thoughts
who should use it and why and how. Otherwise simulations how that
thing could do a FIR-filter or a fourier transform ( via Chirp-Z )
would have been done and a application notes about it would be
ready now.
On the other hand the machine of Chip Gracey has vast amounts
of SRAM ( 32kByte ), is easier to understand by the average user
and a better fit to his needs.

Beeing low volume ( <500 ) patching a-ready-to-run
hardware on a FR4 carrier board its doable by stackprocessor
on FPGA. Even a controller with FORTH-in-ROM/FLASH would
be applicable. Kickstarter / indiegogo is not about fancy
technology.
