Basically I just want a SPFx Content Editor WebPart where they can do anything they have done with SharePoint for the past 10 years.
Please correct my wrong assumptions:
- SPFx development can only be done with (thorough) TypeScript knowledge (and the whole dev stack)
- Any external library (eg. 3rd party jQuery libraries) needs .d.ts definition declarations
- 3rd party ES5 Libraries that are not strongly typed and interact out of their box (into DOM) might cause problems
- Its cheaper to 'let the team go' and find people with above skills
