What is feature management? Feature management is a new class of software development tools and techniques powered by feature flags. A feature flag is a lever of control within your code (an if-else statement) that decouples code deployments from feature releases. Developers have used some variation of feature flags for years. But when it comes to enjoying the full benefits of feature flags, many have only scratched the surface. At most organizations, the art of feature flagging is confined to just a few teams across a few use cases. Such limits stem, in part, from the fact that managing feature flags at scale is quite challenging. For one thing, technical debt can rapidly accrue if you start using flags in large volumes. As a result, only a handful of developers end up using them, thus limiting the value an organization can capture from those flags (see what we did there?). Another drawback of conventional flags is they only support basic true-false, or Boolean, use cases. This, too, prevents organizations from realizing the full benefits of feature flags. ...

拆分为两套代码所存在的问题： 使用不同分支后，大型修改的合并将变得极为困难，不论是从上游合并到下游，还是下游合并到上游，都将成为一个耗时巨大的工程，以轻共享代码合并上游为例，历时3个多月，经历过大量测试，仍然出现风险不可控。如果只是禁绝了从下游合并到上游的可能，下游的客户也一样需要承担上游合并到下游所带来的功能异常风险，及下游代码丢失的风险，该风险从宏观和微观层面，都与下游合并至上游一致。 ...
