Currently it is not possible to pass params attribute to @command() and @group() decorators.
This would be really simple implementation, which can be seen in this forked commit

Although, this allows to mix decorator and class patterns, there are a few advantages as well:

1. Share same option spec between (sub)commands (consider CRUD subcommands which all have --force option, except read)
   It can be done with nested decorators, which hurt readability
2. Take advantage of IDE auto-completion when using Option() class instead of decorator (PEP-612 would resolve this, but it requires python >=3.10)

If this is something to be considered, I can follow up with a PR.

Example usage:

import click

@click.group()
def crud():
    ...

write_args = [
    click.Option(['--force'], is_flag=True)
]

@crud.command(params=write_args)
def create():
    ...

@crud.command(params=write_args)
@click.option('--create', is_flag=True) # Should this be appended or prepended to `write_args`?
def update():
    ...

@crud.command(params=write_args)
def delete():
    ...

@crud.command()
def read():
    ...
