Yes, this is application/UI/UX issue, from programmers' point of view, 
it's up to me, whether I decide to give user the possibility to choose 
file (path) or whether I siply open some kind of file stream somewhere 
and write into it. But that is not possible for web apps due to 
security. But this could be a way for JS API. Give blob/file/stream both 
functions and the first call of either save or saveAs on such object 
would always trigger Save As dialog, subsequent call to save() would 
only flush data on disc, while saveAs() would trigger the dialog again, 
write to new file and assign new file name for subsequent save() calls. 
Unless I missed something, Blobs/Files cannot be changed once created, 
but this could & should work for streams at least (because always 
forcing user to select the same file over and over again is poor 
design... application already has been granted acces to certain file).
BTW it would be great if application could get some persistent disc file 
URN and persistent priveleges to it (if user select file once, 
application would be able to asses such file always (in next session) 
without user having to select it once again, the same for writing), so 
application would only remember files URN (IndexDB, LocalStorage, 
whatever) and access it anytime later. Origin based of course.
