If stropping technique can't be taught or even described, that might explain why it receives less attention on SRP than honing. Nothing can take the place of experience, but those who have it with regards to honing have devised pyramids, sharpness tests and so on as ways to translate, however imperfectly, knowledge that lives in the hands into knowledge that lives in the head, and can therefore be communicated over the internet.
If it's going to take us 10 years to liberate us from regular honing, then we'll be needing those honing skills in the meantime!
