 That's
exactly what a dedicated mode/account is: you need to go and open yet
 *another* account for reliably using delta.
 If you use your current mail account (shared mode) to log-in in delta, you
 are very likely to encounter bugs and disrupt your mailbox which gets
 filtered unreliably. Which is why developers started recommending using a
 dedicated account. 
  Are you basing this prediction on testing the current F-droid
version (0.100)?
   
  The great majority of people on this list have
expressed perplexities on
 this very recommendation and agree with you.
 Unfortunately we've just finally come to know that it is not a priority to
 mitigate this issue, so the only way to use delta is to create another
 dedicated mail account. 
 Did you get my earlier mail that shared accounts are fully
supported
 and that we think the moving logic has even improved? 
Yes, but improving the
filtering/moving logic wasn't the main issue: as 
I already tried to make you notice 
<https://lists.codespeak.net/hyperkitty/list/delta@codespeak.net/thread/TAQGFUOGXWPNR7UV6ETEUYKDX6UKXZJO/>
(together with the other people which reported the same thing over and 
over mostly on the ephemeral IRC channel at the time) there has always 
been a big *scope* issue with delta-chat, resulting in erroneously 
taking over ownership of conversations.
So unless delta stops 
<https://lists.codespeak.net/hyperkitty/list/delta@codespeak.net/thread/TAQGFUOGXWPNR7UV6ETEUYKDX6UKXZJO/>
to act upon *non-chat messages* I don't see how you can prevent 
unreliable sorting in a mixed/shared account scenario.
If nothing has changed in this regard (I don't see anything related in 
the announcement), I wouldn't recommend people to use delta with an 
account sharing access with other MUAs.
