Chris, STOs may be the buzzword for 2019, and your description of their "limitations" is quite apt. However, Hedera Hashgraph did their crowdsale with an SAFT in August 2018. Perhaps this model would be more appropriate for selling stake in a network as opposed to selling stake in an organization. Remember, Hedera ran towards regulators because of the problems with ICOs. This gives future projects options in the toolbox. Dev teams should always use the right tool for the job, right?
