PostgreSQL & Liquibase - default id value from sequence - database

Question

I generated a changelog.xml from an existent database using Liquibase.
Liquibase 4.9.1
PostgreSQL 13.2
The original database was built using the below commands. One company table that has its primary key id defaulted to the my_company_id_seq sequence nextval
The Liquibase generate-changelog command created two change sets (company table & sequence) but the configured company default id, that used to point to the my_company_id_seq sequence, was lost, now it uses GENERATED BY DEFAULT AS IDENTITY.
I understand GENERATED BY DEFAULT AS IDENTITY is the recommended approach from PostgreSQl 10+ on instead of SERIAL, but not for my use case where sometimes I need to generate the ID in advance (calling nextValue from the sequence) and later pass it at time to insert the data into company table, and other times I can just let the id to be generated by the configured DEFAULT nextval('my_company_id_seq')
Do you know the rationale of it?
Or maybe there is no and it can be considered a bug?
Any insights and/or suggestions will be really appreciated
DDL from existent database:
CREATE SEQUENCE my_company_id_seq

CREATE TABLE company (
id INT NOT NULL DEFAULT nextval('my_company_id_seq') PRIMARY KEY,
name VARCHAR NOT NULL
);
