What will 'change things' is when China makes these and sends 1000 of them to Taiwan all at once with another few thousand in reserve.
The cost/scale/saturation issue hasn't really been explored.
Notably - the 'West' is helpless to support Ukraine because nobody has anything useful except the Americans who have mostly 'super high end gear'.

The other glaring hole is AA - Patriots are really expensive and there's only a few of them, this feels like a weakness to me in that Russia could feasibly strike those and then what?
There's a 'mid market' of gear that needs to be sorted out.
Finally - artillery - it's not going away, we're struggling to get Ukraine what amounts to almost ancient tech.
NATO should have 100's of M777's in reserve, precisely for these occasions, i.e. to lend out as necessary.
