Comment (by konrad.zemek@…):

 I believe this commit fixes the issue in a proper manner:
 https://github.com/kzemek/thread/commit/60bebc5e8325bf1fcdb3b0ecc586ecccd4200208


 It also befriends the nested future specialization with
 {{{make_shared_future_async_continuation_shared_state}}} and
 {{{make_shared_future_deferred_continuation_shared_state}}}, as I found
 that returning a future from {{{shared_future<>::then()}}} also resulted
 in similar compilation errors.
