Well filled your survey interesting enough
Although I do note that consensus of the network
Fungibility and some other things would impact the choices such as anonymity (or pseudo anonymity)

Chargebacks are basically escrow but its a dev thing no need to nitpick just pointing it out sidechains perhaps in the future
Best of luck with your survey
Many many thanks for your help.
And I will note down your valuable comments which might mention in the report.
Thanks again.
