   > 1. what is the current s3 express lifecycle support? Is there some now?
   > 
   >  2. do object prefixes still appear in LIST calls when there are pending 
uploads?
   > 
   > 
   > these are the problems that the object delete stuff is trying to 
address...if it is now consistent with s3 standard then we can turn it off. 
otherwise we have a problem: turning off that purge on delete behaviour 
introduces its own problems
   > 
   > which code is doing the deletion? Can it use the bulk delete API to 
explitictly delete files? there's no extra work there other than the building 
up of the bulk delete POSTs and a bit of rate throttling
   
   2. Yes. Pending MPU path becomes visible (The file becomes visible only 
after complete MPU). I,e let's say we are writing to S3 express bucket - 
s3://<bucket>/path/key/file.txt using MPU - Once the MPU is initiated - The 
path  s3://<bucket>/path/key/ becomes visible and can be listed (file.txt) 
won't be visible
   1. Bucket policy is same as standard buckets. Dangling MPUs can be deleted 
by  AbortIncompleteMultipartUpload bucket policy
