Support for incremental models

[gerardpc]

Context
We are using fal with a python model in SQL Server, and are trying to update the model to an incremental one:

def model(dbt, session):
    """."""
    dbt.config(materialized="incremental")
    ...

However, I'm getting this error when doing dbt run:

09:18:35  Running with dbt=1.3.3
09:18:35  Found 16 models, 7 tests, 0 snapshots, 0 analyses, 438 macros, 0 operations, 0 seed files, 19 sources, 0 exposures, 0 metrics

After some research it appears that incremental models are not yet supported by fal.

Describe the solution you'd like
The possibility to use incremental python models instead of just full table recreations.

Is there an existing feature request for this?
Apparently not, I've been suggested to open one from the slack channel, https://app.slack.com/client/T0VLPD22H/C02V8QW3Q4Q/thread/C02V8QW3Q4Q-1682416894.173549
