Seeding data on before with lifecycle between steps

[BudaPavel]

Good day.

I'm seeding data in database and want to do it on before and not beforeEach.
On seeding data I simplify to commands and I can't store seeded object into alias, as Cypress core logic reset aliases on each step.

My solution is to have a global variable that would store my seeds and would be accessible between steps (sample bellow).
Questions:

1. If I understand correctly cy.id is id of each specification instance (when running in parallel)?
2. Maybe there is a downside in such solution that someone can see? (I know that it's definitely not a recommended solution, but don't see a better alternative :) )

Sample commands (support/commands.js):

...
window.seeds = {};

let getSeed = function (cy_id, seed_key) {
    return (seeds.hasOwnProperty(cy_id) && seeds[cy_id].hasOwnProperty(seed_key))
        ? seeds[cy_id][seed_key]
        : null;
}

let setSeed = function (cy_id, seed_key, value) {
    if (!seeds.hasOwnProperty(cy_id)) {
        seeds[cy_id] = {
            user : null
        }
    }

    seeds[cy_id][seed_key] = value;
}

Cypress.Commands.add("createUser", (obj = {}) => {
    cy.task('seeder:createUser', obj).then((user) => setSeed(cy.id, 'user', user))
});
...

Sample usage (demo_spec.js):

describe('Demo seed', () => {
   before(function() {
        cy.createUser()
    });
    
    it('Step 1', function() {
          cy.expect(seeds[cy.id].user).to.not.be.null
    });
    it('Step 2', function() {
          cy.expect(seeds[cy.id].user).to.not.be.null
    });
});
