Except we already know that once Taylor figures out how to make a given type of 'silk', she can produce as much as she wants. It's only a matter of being able to source the necessary materials to make it, and I suspect some of those materials are shard created. Or at least she *thinks* they're created by her power, but we don't know WHAT power is making her able do pull of some of this stuff.
It's not like she's gonna go announcing this to the world. If PRT/Guild wants test & use samples, they'll have to leave her a message. Just writing it out on a sheet of paper in Colin's office would be a good start.
And what part of any of this screams bio-tinker? For all the PRT knows, Taylor is an exceptionally gifted Mech Tinker specializing in insect/arachnid forms.
