Forget about "users", this is an API so think about "applications".
An application wil be just as "surprised" when it runs
svn_client_move foo/bar zig/zag
expecting to create a file zig/zag but getting a file zig/zag/bar.
The application has no reliable way to determine which name will get

I'm suggesting that a sensible API would always be predictable, so the
current "magic" that tests whether dst is a directory should be
deprecated. Thus only the deprecated functions would have the
checking code, the new functions would simply assume that the
destination does not exist and attempt to create the copy, returning
an error if the some existing item prevents the copy.
I'm suggesting that svn_client_move should be modelled on the C
library function rename(2) rather than the program 'mv'. Similarly
svn_client_copy should be modelled on link(2) rather than 'cp'.
Things get more complicated if we want to support multiple source
targets, we know approximately how it should behave but nobody has
worked out the details, see:
