  1. Perfer type(x) is int to isinstance(x, int)

    This covered all additional instances I could see where `x` was
    user-controlled.
    The remaining cases are
    
    ```
    $ rg -s 'isinstance.*[^_]int'
    tests/replication/_base.py
    576:        if isinstance(obj, int):
    
    synapse/util/caches/stream_change_cache.py
    136:        assert isinstance(stream_pos, int)
    214:        assert isinstance(stream_pos, int)
    246:        assert isinstance(stream_pos, int)
    267:        assert isinstance(stream_pos, int)
    
    synapse/replication/tcp/external_cache.py
    133:        if isinstance(result, int):
    
    synapse/metrics/__init__.py
    100:        if isinstance(calls, (int, float)):
    
    synapse/handlers/appservice.py
    262:        assert isinstance(new_token, int)
    
    synapse/config/_util.py
    62:        if isinstance(p, int):
    ```
    
    which cover metrics, logic related to `jsonschema`, and replication and
    data streams. AFAICS these are all internal to Synapse
