There're few issues around using +d,-d with the intent to increment and restore the former+d, keyword adds the very first keyword and by thus activates the statekeyword the following -d,keyword does remove the keyword but leaves the active state for everything, including pollution of the server error log.

BUG#11765644: DEBUG 'D' LIST SHOULD STAY EMPTY AFTER SET
DEBUG="+D,<SYMBOL>"
PROBLEM AND FIX:
When the debug 'd' flag has been set to empty, then all
DBUG_ macros are enabled. But if one then sets debug="
+d,foo" then only foo, all others are turned off. The
expected/intended behaviour should be to add debug for
'symbol' in addition to whatever was enabled before.
The fix adds keyword to the stack of active keyword list
if debug was not enabled for all symbols. Also turn debug
off if the last keyword is removed from the stack of
keywords. NOTE: This shall require a change in the docs
to reflect the changed behaviour in this bug
that addresses that and few more use cases.
