Had Coanda developed his jet

I'm not sure if I brought this up before, but I figured now would be a good time to do it again.

What if Henri Coanda had developed his 1910 jet biplane further?

Or, if he didn't have sufficient funds to do so, what if another manufacturer had helped him along, say, Junkers, or even Sopwith?

As many people have been saying over the years that WW1 was the first air war, what might have transpired had reaction motors been developed sufficiently to enter into the conflict?

WW1 as the first jet air war?

Had materials technology developed far enough back then for jets to work properly?

Even Whittle had to wait a while before Inco developed the alloys that allowed him to get decent flame temperatures for his engines. I guess that Ohain was in the same situation in Germany too.

The relatively poor results of similar later internal combustion engine driven compression-jet powerplants,
like the Campini-Caproni and various Russian VDK designs - Coanda's 'engine' was not a turbo-jet,
demonstrate that it was unlikely that Coanda's more primitive version would have been an effective
powerplant in the WWI era, regardless of who came onboard. Indeed when compared to the C-C and VDK
designs Coand'as had a number of inherent flaws. Also as there is zero independent confirmation that his
'jet aircraft' actually flew the whole project is questionable.

Coanda's "engine" was a ducted fan with "afterburner", much like the later Caproni-Campini N1.

But, as this is a speculative forum, I am simply asking what if, someone else saw promise in Coanda's idea and took it from there.

Except that it wasn't a 'ducted fan' with an 'afterburner', nor BTW was the engine of C-C N-1.

Coanda's compressor disc 'propeller' (his word) design was very different, look at the various patents
and you'll see that the air and gas flow was not 'straight through' like a 'ducted fan'. The design was
based on water and steam turbine principles and involved compression and expansion.
