How to avoid huge setup scripts?

Question

The approach I've seen so far to handle setup scripts is the version_compare:

namespace My\Module\Setup;

class UpgradeSchema implements \Magento\Framework\Setup\UpgradeSchemaInterface;
{

    public function __construct(
        \My\Module\Model\SomethingFactory $somethingFactory,
        \My\Module\Model\AnotherThing $anotherThing
    ) {
        $this->somethingFactory = $somethingFactory;
        $this->anotherThing = $anotherThing;
    }

    public function upgrade(\Magento\Framework\Setup\SchemaSetupInterface $setup, \Magento\Framework\Setup\ModuleContextInterface $context)
    {
        $setup->startSetup();

        if (version_compare($context->getVersion(), '1.0.0', '<')) {
            // do stuff with $this->somethingFactory
        }

        if (version_compare($context->getVersion(), '1.0.1', '<')) {
            // do stuff with $this->anotherThing
        }

        $setup->endSetup();
    }

}

At some point in the life of a module, those scripts can become huge and very hard to maintain, and the dependencies injected might change over time, but you'll need to keep all of them in order to guarantee a safe upgrade from each particular version you have published.

Is it known any other possible approach to manage the setup scripts?

Thanks!

Split it to set of classes.

Like UpdaterTo100, UpdaterTo101, ...
