So our Prospect want to implement Tokenized Sending Features because they don't want to store data in SFMC before sending Email/SMS and want to use REST API to push data into SFMC but again they want to use journey builder activities, new tokens creation and other data filter and segmentation/query features etc but my concern after looking at below unsupported features on SFMC documentation is, How to to resolve following listed limitation ? is there any solution to this ? can we still use journey builder if we enable tokenized sending? 
 
Unsupported Tokenized Sending Features:
Tokenized Sending does not work with certain Marketing Cloud features. Review this list for additional information.
MobilePush, GroupConnect, or Marketing Cloud Connect
MobileConnect QueueMO SMS API
Other data privacy features, such as field-level data encryption or data obfuscation
Journey Builder activities when not storing decision criteria in a clear state or in Marketing Cloud
Segmenting, filtering, or querying when not storing criteria in a clear state or in Marketing Cloud
Execution of Service Level Agreements (SLAs) specifically for sending due to the inclusion of outside servers within the process
New token creation from a clear email address or mobile number. For every use case, create a token.
