I see that burt’s constraint is supported by igraph and I wonder why Burt’s effective size is not supported.

Is this something currently under develop?

It doesn’t seem planned right now, but you could open a new feature request here:

> **[Build software better, together](https://github.com/igraph/igraph/issues/new/choose)**
>
> GitHub is where people build software. More than 100 million people use GitHub to discover, fork, and contribute to over 330 million projects.

It could take a long time before it’s implemented, since we have a lot of feature requests already. Any help is always appreciated.
