I mean the fact that Drax is not solvent without UK government funds and the fact they have to import wood pellets from Canada/US should give you a pretty good idea that none of this is sustainable or carbon neutral. I would much rather see those funds allocated to actual renewable sources instead of wasting time/money with wood furnaces and arguing if they are sustainable/renewable.

If those funds can get the company to close coal production and use wood pellets instead that is certainly a big step forward.

I doesn't indicate that at all. "Sustainable" from a business point of view and "Sustainable" from a carbon production point of view are two entirely different things.
