The RemoveExceptionFrameVarsIntegration, when enabled depending on configuration, removes function calling arguments from exception stacktraces, but does not remove them from event stacktraces - which may be added automatically to events (e.g. transactions) by \Sentry\Client::addMissingStacktraceToEvent().
Enable stacktraces and performance tracing, disable "reflection tracing" (function calling arguments). Observe that the transaction events have a stacktrace with function calling arguments.
Although the event stacktrace may not be an "exception" stacktrace per se, the RemoveExceptionFrameVarsIntegration could remove the function calling arguments from event stacktraces as well.
