Well I'd like to offer a different perspective.
I am autistic, and therefore was an autistic child. I am late diagnosed, although all the signs were there from being a child.
I didn't get extra support.
I entered the workforce, and for the first few years also didn't get support.
Then I was diagnosed, and I asked for support but by then my support needs were far too significant for a workplace to reasonably accommodate.
I had experienced a significant skill regression. I didn't know it was possible to lose skills you have automatically acted upon most of your life but I did.
The fact is no amount of early support will stop autism being a disability. It might lessen the impact, it might sustain someone for longer, but if you're autistic you will always be autistic. Removing social scaffolding early doesn't create resilience it creates trauma.
We will always have some social, communication and interaction deficits that make the corporate working world a nightmare for us. Our facial expressions might not match our feelings, our tone might not match our words, we might be less verbal, or overly verbal as we outwardly process information and that can be very grating for others to cope with, we might need to understand why something needs to be done in order to do it as opposed to just being told what to do and this can be seen as a challenge on authority or not respecting hierarchies, simply because we are bottom up thinkers, we might have sensory issues that cause us daily discomfort that others around us cause and insist it is for their comfort that they must, like lighting and music and windows being open or closed or eating smelly foods, or uniform policies that make no sense or presenteeism for the sake of presenteeism. It might be communication going off script and needing extra time for processing information with imposed deadlines that you just can't meet with the high pressure.
There's nothing you can do to an autistic child by adding or removing that social scaffolding that makes the working world more tolerable, but by keeping support in place when they are children, you're significantly reducing trauma which allows them time to gain skills that could benefit them later in life.
