For ST_Simplify, ZM behaviour when simplification occurs may not be correct:
```python
# Linestring with Z: large tolerance removes intermediate vertex
pytest.param(
"LINESTRING Z (0 0 100, 5 1 150, 10 0 200)",
200000.0,
"LINESTRING Z (0 0 100, 10 0 200)",
id="linestring_z_simplify",
),
# Linestring with M: large tolerance removes intermediate vertex
pytest.param(
"LINESTRING M (0 0 100, 5 1 150, 10 0 200)",
200000.0,
"LINESTRING M (0 0 100, 10 0 200)",
id="linestring_m_simplify",
),
# Linestring with ZM: large tolerance removes intermediate vertex
pytest.param(
"LINESTRING ZM (0 0 100 1000, 5 1 150 1500, 10 0 200 2000)",
200000.0,
"LINESTRING ZM (0 0 100 1000, 10 0 200 2000)",
